  • 1. Pulmonary T.B Pneumonia Lung Abscess Influenza Presenter: Shahina Amiry Sr. Instructor AKUSON
  • 2.
    • Definition:
    • TB is a bacterial infection caused by Mycobacterium tuberculosis. It most commonly affects the lungs, producing pulmonary TB.
    • Cause:
    • Gram +ve Mycobacterium
    • tuberculebacilli.
    06/07/09 www.health-nurses-doctors.com
  • 3. Pathophysiology
    • Susceptible person inhaled the organism
    • The organism settles in the alveoli and multiply
    • The organism may also transport through blood stream and lymph system to other parts of the body
    • The body immune system respond by initiating inflammatory process and phagocytes take place
    • The tissue reaction causes accumulation of the exudates into the alveoli and causes bronchopneumonia
    06/07/09 www.health-nurses-doctors.com
  • 4.
    • Granulomas are formed which transformed into the fibrous tissues
    • The bacteria and macrophages become necrotic and form the cheesy mass
    • Compromised and inadequate immune response, re-infection and activation of dormant bacteria develop active disease
    • Ghon tubercle ulcerate and cheesy material releases into bronchi and bacteria become airborne and cause active tuberculosis
    • Scar tissue form

  • 5. 06/07/09 www.health-nurses-doctors.com
  • 6. Risk factors & Transmission
    • Airborne droplet during coughing, sneezing, spitting, talking, laughing, singing.
    • History of TB, personally, or amongst friends or family.
    • Migration from a country with a high incidence of TB.
    • History of travel to an area with a high incidence of TB.
    • Alcohol and/or drug abuse.
    • Compromised immunity due to illness, e.g., HIV infection.
    • Malnutrition
    • Over crowd

  • 10. Treatment: 06/07/09
  • 11.
    • Medications:
    • Primary Agents Secondary Agents
    • isoniazid* capreomycin
    • ethambutol cycloserine
    • pyrazinamide (PZA) ethionamide
    • rifampin kanamycin

    • *most frequently used
    06/07/09 www.health-nurses-doctors.com
  • 12. Side Effects of Medication 06/07/09 www.health-nurses-doctors.com
  • 13. NURSING PRIORITIES
    • 1. Achieve/maintain adequate ventilation/oxygenation.
    • 2. Prevent spread of infection.
    • 3. Support behaviors/tasks to maintain health.
    • 4. Promote effective coping strategies.
    • 5. Provide information about disease process/prognosis and
    • treatment needs.
    06/07/09 www.health-nurses-doctors.com
  • 14.
    • Diagnosis:
    • Infection, risk for spread/reactivation
    • Airway Clearance, ineffective
    • Nutrition: imbalanced, less than body requirment
    • Knowledge, deficient regarding condition, treatment, prevention, self-care, and discharge needs
    06/07/09 www.health-nurses-doctors.com
  • 15.
    • Infection, risk for spread/reactivation
    • Instruct patient to cough/sneeze and expectorate into tissue and to refrain from spitting.
    • Proper disposal of tissue and good hand washing techniques.
    • Identify individual risk factors for reactivation of tuberculosis
    • Awareness of transmission possibilities help patient take steps to prevent infection of others.
    • Note: AFB can pass through standard masks; therefore, particulate respirators are required.
    06/07/09 www.health-nurses-doctors.com
  • 16.
    • Assess respiratory function, e.g., breath sounds, rate, rhythm, and depth, and use of accessory muscles.
    • Note ability to expectorate mucus/cough effectively, document character, amount of sputum, presence of hemoptysis.
    • Place patient in semi- or high-Fowler’s position.
    • Assist patient with coughing and deep-breathing exercises.
    • Clear secretions from mouth and trachea; suction as necessary.
    • Maintain fluid intake of at least 2500 mL/day unless contraindicated
    • Provide oral care before and after respiratory treatments.
    06/07/09 www.health-nurses-doctors.com
  • 17. Nutrition: imbalanced, less than body requirements
    • Document patient’s nutritional status on admission
    • Encourage selection/ingestion of well-balanced meals.
    • Ascertain patient’s usual dietary pattern, likes/dislikes.
    • Encourage small, frequent meals with foods high in protein and carbohydrates.
    • Monitor I&O and weight periodically.
    • Investigate anorexia and nausea/vomiting, and note
    • possible correlation to medications.
    • Monitor frequency, volume, consistency of stools.
    06/07/09 www.health-nurses-doctors.com
  • 18.
    • Compliance with multidrug regimens for prolonged periods is difficult, so directly observed therapy (DOT) should be considered.
    • Aids in monitoring the effects of medications and patient’s response to therapy.
    • Monitor laboratory studies, e.g., sputum smear results; Liver function studies, e. g., AST/ALT.

  • 25. Pathophysiology organism Susceptible host pneumonia Organism via blood 06/07/09 www.health-nurses-doctors.com
  • 26. Pathophysiology
    • Inhalation of pathogen and harmless bacteria enter into the lower reparatory tract
    • Inflammatory reaction occurs in the alveoli and produces an exudates that interfere with diffusion of oxygen and carbon dioxide.
    • The WBCs especially neutrophills migrate to alveoli and fill the air containing space
    • The area of the lungs are not adequately ventilated because of secretion and mucosal edema
